Is there a way to sync the internal storage with my SD Card? I keep a SD card/usb adapter in the car for music, and I download all my music on my phone now. And I would like to be able to just put my Cars SD Card in my phone and sync it instead of bringing it in to the computer all the time to put music on it? And I don't want to manually copy the music because thats just too much work haha and then stuff gets messed up. So is there an app for that?
